FIREPLACE.

Specification of Letters Patent.

Patented June 29, 1909.

Application filed April 11, 1907. Serial No. 367,680.

To all whom it may concern:

Be it known that I, \VALTEP. W. GUY, a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Fireplaces, of which the following is a full, clear, and exact description.

The invention relates to fireplaces.

In the construction of fireplaces the chimney-flue is usually offsetwith respect to the fire-chamber and is usually smaller in area than said chamber and a damper is usually provided for controlling or regulating the draft, being usually set in a throat and interposed between the top of the fire-chamber and the flue. Usually the top wall of the throat connecting the fire-chamber and the flue is formed of brick, concrete orthe like, and this is objectionable because it does not provide a smooth surface or lining along which the products of combustion will pass without accumulation, the wall thereof being usually roughly made. Sometimes a plaster lining is applied to the throat wall and this is objectionable in that it is disintegrated by the heat. Furthermore, in forming the arch of the fireplace some care must be exercised in laying the brick and in some instances a metallic cross-support is provided for the arch. Furthermore, in the construction of the chamber or throat between the flue and the fire-chamber it is desirable to provide means for cutting off connnunication with the flue to prevent back-draft from causing the soot to be blown into the fireplace and room. 4

The invention designs to provide an improved dome-or thrmit-corsiruction for the fireplace having a damper mounted therein which can be readily laid in its proper place by unskilled labor and \thich will cover practically the entire areaof the throat to form a dome which provides a complete metallic top for the fire-chamber and which serves as a support for the arch over the fireplace, and thus insures a top ordoine of proper formation. In other words, to provide an improved dome which serves as arch and damper-support and which forms a lhroat-plate completely lining the back of the arch and is propcrly shaped to produce the desired draft and wluch may be regulated as desired.

Another ob ect is to provide a dome in which the damper is so arranged that it is inclined when open to direct all of the products of combustion to the top of the dome so that it will effectively regulate the draft without eliminating the defiective effect of the damper in conjunction with the l-intel or fixed inclined walls of the dome.

The invention also designs to provide a construction and arrangement of the damper struction hereinafter set forth and more par-1 ticularly defined by claim at the conclusionhereof.

In the drawings: Figure 1 is a verticah section of a fireplace embodying the invention. Fig. 2 is a plan view of the dome and damper. Fig. 3 is a vertical section on line 3-3 of Fig. And Fig. at is a detail vertical section of a modified form of the invention.

The fireplace comprises a floor or bed 10, a baclmvall 11 having its upper portion 12 inclined or pitched to deflect the heat forward through the front opening of the fireplace and an arch-wall 13 above the front opening. chimney-flue lat is usually arranged in the back part of the fireplace and offset with respect to the fire-chambcr and conmuniicates with the top of the fire-chamber to carry away the products of combustion through a throat or passage 15. A metallic dome is set into and supported by the back-wall and side-walls of the fireplace and has a bascflange It, extending around the bottom thereof. The back rail of said, flange is adapted to rest on the top of the projecting portion 12 of the back-wall and the side-rails of said flange are adapted to be embedded in orsupported by the side-walls of the fireplace and the 'l'rontrail 17 of the flange is adapted to support the arch-wall over the frontopening of the fireplace. The sides of the fireplace are usually angled so that tho fire-chamber is wider at its front than at its rea and the side rails of the base flange are correspondingly angled. In constructing the fireplace the walls are laid to the top level of the firechamber and the dome-plate is then set thereon. The rear-railiand side-rails of the i The dome has integrally formed therewith a" flange supportt lie dome and the front rail of the flange serves as a support on which the arch may be-ieadily and quickly laid.

lintel. '18 which is inclined upwardly and rearwar'dly and forms a metallic lining for the throat as well as an extensive support for the arch-wall. The'lintel 1S ofthe dome- "is pi'ovided with a rib 19. adjacent its upper end and a rib 20"which'matei i-aiystrengthen it to' better the :arch 'wall th'e ribs being properly disposed so that the brick of the wall may rest thereon and so .the ribs will serve as guides for laying the bricks in horizontal aline'ment. The first. course of. the

archis usually laid on the base flange 17, the

next course 'on rib 20, and the next on rib 1'9 at'peak-of the-dome. The 'lintel extends to a peak or apex of the dome;and the dome e'X tends downwardly and 'rearwardly'froin the peak as at 21, and has sidewalls-22. which are tapered and integrally formed with-the .idome. opening 23 is formed in the back it? the dome for-the escape of the roducts of combustion and a damper '24:.is a apted to. close the opening When the fireplace is not in' use, or vto vary the opening to correspondingly regulate the draft. A holder 25 is pivota'lly connected to the damper asat 26 and is providedwithteeth 27 adapted to-engage'a lug 28 integrally formed with the lintel of the f dome and whereby the damper. may, beheld in different positions. The front end of theholder is usually provided with an eye 29"so extends forwardly and upwardly Ltroin its, hingedend anito the peak of the doineyahd thus ham er the fireplace is formed by the integral vlint'el and side walls of the dome and the'damper; the opening for the escape of the products of combustion being located at the peak'o'f the dome to. provide a dome construction: in which a draft is created which draws the products of combustion fire chambc'nl Some of the nets 9f combustion defiectedforwardly by the pitched wall 12 are defiected egainst thelintel 18 which directs them to the exhaust opening at the peak ofthe dome and'this construction avoids pockets n wliichunconsumed ases or prodi'icts canaccumul'ate, and

'the walls of the dome are all shaped to 'dij rect'the products through .the opez ing at the. peak of tlie dome, tending to produce a draft which carries away the products from the-fire-chamber. T hefeature of providing a dome-plate comprising a sloping lintel and a reversely sloping damper. which swings about its lower end to provide an exhaustopening at-the peak of the dome, is an important one because it produces a'n'even draft throughout the entire area of the up per portion of the fire-chamber, which can 4 trolled by the damper is wider at the pealr than at its lower end and the .damper is corfrcspondingly formed and this construction also aids 'in providing a better and uniform draft for the products. of combustion, 'because-all of the products are'drawn to the peak or. upper portion of the-dome at the 'mouth'of the opening between the upper end of the damper and the peak when the damper is open' and because little or no direct draft is created near thebackwall of the fireplace aswould occur ifthe'opening were narrower at the'lower' end than atth'e upper end, bet:

'-ter combustion being attained when there is substa'ntiallyno draft the, rear Wall."

As a're sult of the construction in which immediately adj acent the damper is pivoted at its lower end and i in the'dome, any soot which may fall'on the top o'f the damper will be directed to the pocket formed between the back wall and the damper and not pass into the fireplace as frequently occurs when thereis'back-draft in the chimney-flue,

Een'eath the. front rail17 of the base 16 isiprovided a longitudinally extending" rib In some instances it isdesirable, particu larly whenthe-throat is to be arranged; I

some distance in backof the front of the fireplace, to .support an angle-iron 84 in they .side- Walls of the fireplace. stancesitis also desirable t'o-position the dome some distance above the lower edge In some i-n-' of thevarch wall as shown in Fig. 4 of the drawings. Rib is formed on thebas'e-of 'the'dome'and not only strengthens the domebut positions the dome on an angle-bar 34 to form a joint which-preventsthe-products from permeating the walls above the dome.

The damper may, by disconnecting the holder, be lifted outof the pintle-seats and withdrawn through the opening in the dometo rovide'rea'dy access to the fluewhen it' from all portionsof the up'ier part of the .is d

eatendjpr'odesired forfcleaning, Obviousl the invention provides a dome which, can' lfirogreadily set in proper position -in the, -firepiace duringthe course of construction, serves as a support for the arch wall and in which the damper opening .s

disposed to: produce a uniform. di a throughout the upper area of the fire-chanirestricted to the details shown and described wall of the fire-place, a flange at the base of but may be modified without departing from the spirit and scope of the invention,

Having thus' described the invention, what I, claim as new'and desire to secure by Let-- ters Patent, is: v 4
